Convective Discussion…
A ridge of high pressure dominates Atlantic Canada today, with the exception of a weak shortwave and associated 250 mb jet moving over central Labrador. This shortwave will provide just enough lift to initiate surface-based convection this afternoon across much of Labrador, however these thundershowers are expected to remain non-severe due to a lack of mid to low level shear, as well as an approaching thermal ridge. The main threats with these thundershowers will be locally heavy downpours of 10-15 mm.
